Mybatis 的foreach 可以巢狀嗎？
- http://code.google.com/p/mybatis/source/browse/trunk/src/test/java/org/apache/ibatis/submitted/nested/?r=3467
- Junit Test
- NestedForEachTest.java
- NestedForEach.xml
照著這個效果,我在自己的paohe專案xml中這樣寫
<select id="queryQualityCost" parameterType="com.itonghui.biz.qualityclient.model.QualityClient" resultMap="BaseResultMap">
SELECT
<include refid="Base_Column_List" />
FROM spot_quality_cost
WHERE QUALITY_COST_ID IN
<foreach collection="qualitySampleinfoList" item="qualitySampleinfo" open="(" separator="," close=")" >
<foreach collection="qualitySampleinfo.qualityVarietyList" item="qualityVariety" separator="," >
#{qualityVariety.qualityCostId}
</foreach>
</foreach>
</select>
java程式碼:
QualityClientServiceImpl.java:
QualityClient qualityClient = new QualityClient();
qualityClient.setQualitySampleinfoList(sampleInfoListTmp);
List<QualityCost> qualityCostList = qualityCostMapper.queryQualityCost(qualityClient); //獲取最新的檢測項費用
其中QualityClient.java vo類有 private List<QualitySampleinfo> qualitySampleinfoList; //樣品列表,
QualitySampleinfo.java vo類有 private List<QualityVariety> qualityVariety;
最終sql效果是
SELECT QUALITY_COST_ID, QUALITY_DESC_ID, QUALITY_CHECK_ID, INSPECT_ORGANIZATION
_ID, TESTING_COST, CHECK_TYPE, IS_STANDARD_SAMPLE, REMARK, ALIVE_FLAG FROM spot_quality_cost WHERE QUALITY_COS
T_ID IN ( ? , ? , ? , ? , ? , ? )
mybatis多個foreach巢狀查詢成功!
